BACKGROUND Technical Field

The present invention relates to security and more particularly to baby detection for electronic-gate (e-gate) environments.

Description of the Related Art

Baby detection is task that can be useful in a variety of applications. Previous methods for baby detection have mostly relied on laser-based sensors that identify the presence of a person in an electronic-gate (e-gate) system by detecting legs. Such methods are not applicable to identifying any person that is not standing on the ground such as, for example, babies that are often carried by an adult on their arms thus suspending the baby's feet in the air and thwarting such laser-based sensors. Thus, there is a need for an improvement to current baby detection systems.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The present invention is directed to baby detection for electronic-gate (e-gate) environments.

In an embodiment, an image-based baby-head detection method is provided that can robustly identify the presence of a baby as long as the baby is visible to a camera.

In an embodiment, the present invention automatically identifies the presence of a baby in a live stream video for an automated electronic-gate (e-gate) system such as can be found at a location of immigration. In an e-gate application, a person might appear together with a baby who requires a manual identification process. Automatically identifying the presence of a baby is critical in such an application in order to achieve a high throughput as well as a high security. The baby may appear in various different configurations and/or postures in a video. The identification system needs to be run at high frequency in order to meet the real-time requirement.

In an embodiment, the present invention performs baby detection by applying a highly accurate and efficient image-based baby head detection method. The method identifies the presence of a baby by detecting the baby's head in images recorded by one or more cameras. In an embodiment, the method can use a deep neural network based detection algorithm for high reliability. In an embodiment, the present invention can provide a recognition result in real-time.

The system 100 includes a camera system 110. While a single camera system 110 is shown in FIG. 1 for the sakes of illustration and brevity, it is to be appreciated that multiple camera systems can be also used, while maintaining the spirit of the present invention.

In the embodiment of FIG. 1, the camera system 110 is mounted on a mounting entity 160. For the sake of illustration, the mounting entity 160 is a pole 180. While a pole 160 is shown for the sake of illustration, any other mounting entity can be used, as readily appreciated by one of ordinary skill in the art given the teachings of the present invention provided herein, while maintaining the spirit of the present invention. For example, the camera system 110 can be mounted on a building, and so forth. The preceding examples are merely illustrative. It is to be appreciated that multiple mounting entities can be located at control hubs and sent to a particular location as needed.

The camera system 110 can be a wireless camera system or can use one or more antennas included on the pole 160 (or other mounting entity (e.g., building, drone, etc.) to which the camera system 110 is mounted or proximate).

The system 100 further includes a server 120 for smuggling detection that involves smuggling using a “fake” baby. The server 120 can located remote from, or proximate to, the camera system 110. The server 120 includes a processor 121, a memory 122, and a wireless transceiver 123. The processor 121 and the memory 122 of the remove server 120 are configured to perform smuggling detection based on images received from the camera system 110 by the (the wireless transceiver 123 of) the remote server 120. To that end, the processor 121 and memory 122 can be configured to include components of an image-based baby detection system. In this way, the presence of a baby 171, carried by a person 170, can be recognized as well as the presence of a non-baby being presented as a baby for a smuggling purpose.

Accordingly, some exemplary suitable environments to which the present invention can be applied can include any environments where smuggling detection can prove useful such as border crossings, transportation hubs, airports, ship ports, and so forth. It is to be appreciated that the preceding environments are merely illustrative and, thus, other environments can also be used, while maintaining the spirit of the present invention.

FIG. 2 shows another exemplary system 200 for baby detection, in accordance with an embodiment of the present principles. System 200 can represent an implementation of system 100, in accordance with an embodiment of the present invention.

The system 200 includes a baby detection system 220 and a computer processing system 240.

The computer processing system 240 essentially controls the other systems of system 200, including the baby detection system 220.

The baby detection system 220 recognizes babies from images and/or video.

The computer processing system 240 performs functions relating, for example, but not limited to: (i) processing baby detection results; (ii) performing one or more actions based on the baby detection results.

The baby detection system 220 and/or the computer processing system 240 can include a camera. For the sake of illustration, a separate camera 271 is shown. The camera 271 can capture images/video of the user. The images/video can then be processed by the computer processing system 240 and/or any of the systems under its control. In an embodiment, the camera 271 can be capable of capturing still and moving images. In an embodiment, the camera can acquire images in the visible and/or infra-red spectrum.

The baby detection system 220 and/or the computer processing system 240 can include a display. For the sake of illustration, a separate display 272 is shown. The display 272 can show baby detection information to the user or other personnel (e.g., security personnel).

The baby detection system 220 and/or the computer processing system 240 can include a speaker. For the sake of illustration, a separate speaker 273 is shown. The speaker 273 can provide auditory guidance to the user (e.g., regarding face positioning, and so forth) and/or a local alert that someone is attempting to spoof the system in order to draw attention to that person.

In an embodiment, one or more of the elements of system 200 is implemented in the cloud using a cloud-based configuration.

In the embodiment shown in FIG. 2, the elements thereof are interconnected by a bus(es)/network(s) 201. However, in other embodiments, other types of connections can also be used. Moreover, in an embodiment, at least one of the elements of system 200 is processor-based.

Further, while one or more elements may be shown as separate elements, in other embodiments, these elements can be combined as one element. For example, while the camera 211 is shown as a separate entity from the baby detection system 220 and the computing processing system 240, in other embodiments the baby detection system 230 and/or the computing processing system 240 can include the camera, obviating the need for a separate camera. Also for example, while the baby detection system 220 and the computer processing system 240 are shown as separate entities, in other embodiments, the baby detection system 220 can be included in the computer processing system 240. The converse is also applicable, where while one or more elements may be part of another element, in other embodiments, the one or more elements may be implemented as standalone elements.

Moreover, one or more elements of FIG. 2 can be implemented in a cloud configuration including, for example, in a distributed configuration.

Additionally, one or more elements in FIG. 2 may be implemented by a variety of devices, which include but are not limited to, Digital Signal Processing (DSP) circuits, programmable processors, Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), Complex Programmable Logic Devices (CPLDs), and so forth.

FIG. 4 shows the baby detection system 220 of FIG. 2, in accordance with an embodiment of the present invention.

The baby detection system 220 includes a data collector 401, a data collector 402, a deep learning engine 410, and e-gate application related data 420.

The data collector 401 is for collecting relating to baby dolls (interchangeably referred to herein as “baby doll data”) 401A that is used as potential inputs to a face recognition system.

The data collector 402 is for collecting data relating to real babies (interchangeably referred to herein as “real baby data”) 402A.

Regarding data collector 401, in recognition that baby dolls can be used as spoofing material for baby detection, data is collected regarding baby dolls. In an embodiment, a large variety of data samples, which are commonly used in various applications/scenarios, is collected. In an embodiment, the collected data is preferably provided by using multiple baby dolls having differing visual characteristics (differences in anatomical features, clothes, etc.) and held using different carrying types. For example, in an embodiment, the collected data involves baby dolls with different nationalities, different clothes, and different postures to collect diverse training data.

Further regarding data collector 401, data collection can be performed for different distractor modalities corresponding to different physical spoofing materials to prevent baby spoofing for the baby detection task.

Regarding data collector 402, a large variety of data samples, which are commonly used in various applications/scenarios, is collected. In an embodiment, the collected data is preferably provided by multiple real babies having differing visual characteristics (differences in anatomical features, nationality, clothes, etc.). For example, in an embodiment, the collected data involves babies with different nationalities, different clothes, and different postures to collect diverse training data. The data can be obtained, for example, from the Internet to avoiding overfitting to baby doll heads. Corresponding bounding boxes can be acquired by manually or automatically.

In an embodiment, the data collected by data collectors 401 and 402 is in picture/image form. Of course, other forms can also be used, while maintaining the spirit of the present invention. Moreover, other types of baby spoofing materials can be used, as readily appreciated by one of ordinary skill in the art given the teachings of the present invention provided herein, while maintaining the spirit of the present invention.

The deep learning engine 410 includes a training portion 410A and an architecture portion 410B. The deep learning engine 410 performs deep learning for baby detection.

Regarding the training portion 410A of the deep learning engine 410, in an embodiment, training is achieved by fine-tuning on top of a pre-trained model (e.g., AlexNet's Imagenet pre-trained model). In an embodiment, a multi-task learning process is used that jointly optimizes an object bounding task (e.g., a general object box allocation task) and a specific object detection model task (for baby head and other types of heads). The object bounding task involves assigning bounding boxes to potential objects of interest in an image. Such objects of interest can be babies in accordance with baby detection as disclosed herein. Hence, the object bounding task can be optimized for head detection in general or baby head detection in specific (and thus involving smaller sizes than expected for an adult head). The specific object detection model task detects the presence or absence of a baby with respect to an object of interest identified by the object bounding process using the deep learning model.

Of course, other training approaches can also be used, while maintaining the spirit of the present invention.

Regarding the architecture portion 410B of the deep learning engine 410, in an embodiment, high efficiency with uncompromised accuracy is achieved by adopting a Singular Value Decomposition (SVD) algorithm (e.g., a truncated SVD (TSVD) algorithm) that reduces the number of filters in all layers of the deep learning object detection method. For example, original filters can be decomposed into two compressed filters that result in much fewer computations in all layers (less multiplication). FIG. 5 shows an exemplary application of a TSVD algorithm 520 to an original filter 510 to obtain compressed filters 511 and 512, in accordance with an embodiment of the present invention;

Further regarding the architecture portion 410B of the deep learning engine 410, in an embodiment, all layers of the neural network model including the convolutional layer are compressed. In an embodiment, an AlexNet-based Scale-Dependent Pooling (SDP) detector can be used as the basic model architecture. AlexNet is the name of a Convolutional Neural Network (CNN) running on Graphics Processing Units (GPUs) implemented in CUDA® for visual recognition. In an embodiment, the AlexNet Convolutional Neural Network includes 5 convolutional layers and 3 fully connected layers. Of course, other numbers of convolutional layer and/or fully connected layers can also be used, while maintaining the spirit of the present invention. Moreover, other detectors and architectures can also be used, given the teachings of the present invention provided herein, while maintaining the spirit of the present invention.

FIGS. 6-7 show an exemplary method 600 for baby detection, in accordance with an embodiment of the present invention. Steps 605 through 615 can be considered to correspond to a training stage 600A of method 600, while steps 620 through 625 can be considered to correspond to a recognition stage 600B of method 600, and step 630 can be considered to correspond to a post-recognition stage 600C.

At step 605, provide images of various spoofing materials used for spoofing a baby detection system and images of actual babies.

At step 610, perform data pre-processing on the images. The pre-processing can involve image contrast enhancements, normalization, cropping, data augmentation, and so forth.

At step 615, train an image-based neural network using the images to form a deep learning model. Preferably, the image-based neural network is trained using the images pre-processed by step 810. In an embodiment, the input images without pre-processing could be used or both the un-pre-processed and the pre-processed images could be used, depending upon the implementation. In an embodiment, the image-based deep learning model is trained based on an already formed neural network or can be created from scratch in this step, as readily appreciated by one of ordinary skill in the art given the teachings of the present invention provided herein, while maintaining the spirit of the present invention. As is evident to one of ordinary skill in the art, efficiency is enhanced when an already existing (object detection-based) neural network is used as a starting point, where such neural network can then be optimized to perform baby detection in accordance with the present invention.

At step 620, receive an input image of a baby to be recognized.

At step 625, perform a baby detection process on the input image using the deep learning model. In an embodiment, the baby detection process of step 625 can involve, for example, performing a multi-task operation that involves a task pair that includes an object bounding task and a specific object detection task (a baby's head). The object bounding task can be used to identify objects and place bounding boxes or other bounding designators (hereinafter “designators” in short) around the identified objects and the specific object detection task can then be applied to the objects in the boxes/designators to avoid having to process the whole image regarding the second (specific object detection) task. Step 625 can be performed for a specific application. Exemplary applications include, but are not limited to, the following applications: baby detection; smuggling detection; mass transit surveillance; and so forth.

At step 630, perform one or more actions based on a result of the baby detection process. For example, the one or more actions can be directed to one or more of the following: baby detection; smuggling detection; mass transit surveillance; and so forth.

In an embodiment, step 630 can include one or more of steps 630A through 630C.

At step 630A, corresponding to baby detection (e.g., with respect to an e-gate application), perform one or more actions than can include, but are not limited to, one or more of the following: log the detection of the baby for one or more purposes (e.g., including, but not limited to, immigration, head count, capacity (e.g., per weight or per person), etc.); generate a local or remote alarm indicative of the detection of a baby; open a gate to permit access or close a gate to block access; and so forth.

At step 630B, corresponding to smuggling detection, perform one or more actions than can include, but are not limited to, one or more of the following: log the detection of a possibly smuggled item (e.g., a baby, contraband (drugs, etc.) etc.); generate a local or remote alarm indicative of the detection of possibly smuggled item; open a gate to permit access or close a gate to block access (and potentially detain the smuggler until the proper authorities can intervene); and so forth.

At step 630C, corresponding to mass transit surveillance, perform one or more actions than can include, but are not limited to, one or more of the following: log the detection of a possibly dangerous item or a prohibited item; generate a local or remote alarm indicative of the detection of a possibly dangerous item or a prohibited item; open a gate to permit access or close a gate to block access (and potentially detain an involved individual until the proper authorities can intervene); and so forth.

As is evident to one of ordinary skill in the art, the action(s) taken is(are) dependent upon the type of application to which the present invention is applied.

FIG. 8 shows an exemplary system 800 for baby detection for electronic-gate (e-gate) environments, in accordance with an embodiment of the present invention.

The system 800 includes a camera system 810. While a single camera system 810 is shown in FIG. 8 for the sakes of illustration and brevity, it is to be appreciated that multiple camera systems can be also used, while maintaining the spirit of the present invention.

In the embodiment of FIG. 8, the camera system 810 is mounted on a mounting entity 860. For the sake of illustration, the mounting entity 860 is an arch structure 860 having a controlled gate 861. The gate 861 can be normally closed and then opened based on a recognition result regarding the person 870 attempting to gain access to the facility. While an arch structure 860 with a gate 861 is shown for the sake of illustration, any other mounting entity can be used, as readily appreciated by one of ordinary skill in the art given the teachings of the present invention provided herein, while maintaining the spirit of the present invention. For example, the camera system 810 can be mounted on a building, a pole, and so forth. The preceding examples are merely illustrative. It is to be appreciated that multiple mounting entities can be located at control hubs and sent to a particular location as needed.

The camera system 810 can be a wireless camera system or can use one or more antennas included on the arch structure 860 (or other mounting entity (e.g., building, drone, etc.) to which the camera system 810 is mounted or proximate).

The system 800 further includes a server 820 for baby detection, e.g., for e-gate environments. The server 820 can located remote from, or proximate to, the camera system 810. The server 820 includes a processor 821, a memory 822, and a wireless transceiver 823. The processor 821 and the memory 822 of the remove server 820 are configured to perform baby detection based on images received from the camera system 810 by the (the wireless transceiver 823 of) the remote server 820. To that end, the processor 821 and memory 822 can be configured to include components of an image-based baby detection system. In this way, the presence of a baby 871, e.g., in a baby carriage 870, can be recognized, as well as the presence of a baby 871, e.g., being carried by a person 880 (and thus, the baby 871 having their legs suspended in the air as shown in FIG. 8, a configuration that thwarts prior art approaches).

Accordingly, some exemplary suitable environments to which the present invention can be applied can include any e-gate environments where baby detection can prove useful such as border crossing, airports, ship ports, and so forth. It is to be appreciated that the preceding environments are merely illustrative and, thus, other environments can also be used, while maintaining the spirit of the present invention.

FIG. 9 shows an exemplary system 900 for mass transit surveillance, in accordance with an embodiment of the present invention.

The system 900 includes a camera system 910. While a single camera system 910 is shown in FIG. 9 for the sakes of illustration and brevity, it is to be appreciated that multiple camera systems can be also used, while maintaining the spirit of the present invention.

In the embodiment of FIG. 9, the camera system 910 is mounted on a mounting entity 960. For the sake of illustration, the mounting entity 960 is a pole 980. While a pole 960 is shown for the sake of illustration, any other mounting entity can be used, as readily appreciated by one of ordinary skill in the art given the teachings of the present invention provided herein, while maintaining the spirit of the present invention. For example, the camera system 910 can be mounted on a building, and so forth. The preceding examples are merely illustrative. It is to be appreciated that multiple mounting entities can be located at control hubs and sent to a particular location as needed.

The camera system 910 can be a wireless camera system or can use one or more antennas included on the pole 960 (or other mounting entity (e.g., building, drone, etc.) to which the camera system 910 is mounted or proximate).

The system 900 further includes a server 920 for mass surveillance detection that involves detecting the presence of a “fake” baby (which can potentially represent a dangerous condition such as, but not limited, to, someone having a dangerous or prohibited object (explosives, drugs, etc.) on their person). The server 920 can located remote from, or proximate to, the camera system 910. The server 920 includes a processor 921, a memory 922, and a wireless transceiver 923. The processor 921 and the memory 922 of the remove server 920 are configured to perform mass surveillance detection based on images received from the camera system 910 by the (the wireless transceiver 923 of) the remote server 920. To that end, the processor 921 and memory 922 can be configured to include components of an image-based baby detection system. In this way, the presence of a baby 971, carried by a person 970, can be recognized as well as the presence of a non-baby being presented as a baby for an undesirable and/or potentially dangerous purpose.

Accordingly, some exemplary suitable environments to which the present invention can be applied can include any environments where mass transit surveillance can prove useful such as border crossings, subways, transportation hubs, airports, ship ports, and so forth. It is to be appreciated that the preceding environments are merely illustrative and, thus, other environments can also be used, while maintaining the spirit of the present invention.

A description will now be given of some of the many attendant advantages of the present invention, in accordance with one or more embodiments of the present invention.
